PAPER-ACTUATING DEVICE FOR BARBERS CHAIRS.

To all whom it may concern: 1

Be it known that 1, DAVID B. Brown, citizen of the United States, residing at Bellingham, in the county of Whatcom and State of Washington, have invented certain new and useful improvements in Paper-Actuating Devices for Barber-Chairs, of which the following is a specification.

This invention relates to chairs and has particular reference to a sanitary attachment to be applied to barbers chairs.

An object of this invention is to provide means for automatically furnishing a strip of paper upon the head-rest of chairs of this nature for each customer and of providing means for admitting of the tearing off of the portion of paper last used for the reception of lather during the shaving of the occupant within the chair.

The invention has for another object the provision of a simple device which actuates a pair of rollers disposed upon the back of a chair to draw the paper over the head-rest from the cylindrical casing in common use, which is positioned upon the front of the heads-est immediately beneath the same and which is adapted to draw a predetermined amount of the paper over the head-rest.

The invention further provides a device of this character which is adapted for operation upon the reciprocation of the back of the chair and one which is adapted for detachment from the chair when the head-rest is removed.

The invention still further aims the provision of a device of this nature which may be applied to chairs of common construction and which do not necessitate any peculiar formation of the parts of the same but which is adaptable for operative relation by simply securing the several parts of the device upon the chair by screws or bolts of common construction.

For a full understanding of the invention, reference is to be had to the following de scription and accompanying drawings, in which,

Figure 1 is a perspective view of the rear of a barbers chair disclosing the back in a raised posltion and having the improved device applied thereto. Fig. 2 is a rear elevation of the back of a barbers chair having the device attached thereto, and Fig. 3 is a detailed sectional view of the pawl and Specification of Letters Patent.

Serial No. 481,010.

ratchet mechanism in conjunction with the detachable shaft and gears employed in the device.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings the numeral 10 designates the back of a barbers chair which is provided with an adjustable headrest 11 over which is adapted to be passed a strip of paper 12. The paper 12 is mounted in a cylinder 13 positioned immediately beneath the head-rest 11 at the forward edge thereof and is passed upwardly over the head-rest l1 and depended rearwardly from the same. The back 10 is provided with a frame 14 of any adaptable construction in which are disposed a pair of rollers 15 and 16. The rollers are preferably provided with milled surfaces between which the strip of paper 12 is adapted to be frictionally engaged. The roller 15 is provided upon its outer extremity with a beveled pinion 17 which is adapted to be meshed with a beveled gear 18 which is disposed upon a shaft 19 vertically positioned and depended from the frame 1d at one end thereof. The frame 14 is positioned immediately beneath the head-rest 11 and is supported thereby so that it may be removed from the chair upon the detachment of the head-rest 11. The shaft 19 is carried by the frame 1 1 by means of passing the upper extremity of the shaft through a pro ectlon 20 of the frame 14 and securing the shaft 19 rotatably in such position by means of an adjustable collar 21 mounted upon the upper extremity of the shaft 19 and serving the purpose of preventing the shaft from sliding downwardly through the projection 20. The shaft 19 is provided intermediate of its length with a universal joint 22 for the purpose of admitting of the angular adjustment of the shaft 19 to conform to the adjustments of the head-rest 11. The frame lt is provided upon its rear edge with a series of teeth 23 against which the strip of paper 12 is adapted to be engaged for the purpose of tearing oif portions of the same which are depended from the rollers 15 and 16.

The back 10 is provided with a bracket 21 which carries a beveled gear 25 which is provided with a flanged collar 26 for rotatable engagement within the bracket 24: to support the gear 25 in a horizontal plane. The gear 25 and flanged collar 26 are preferably integrally formed and are provided centrally with a rectangular aperture to slidably engage the lower extremity of the shaft 19 which is formed rectangularly in crosssection. The bracket is also provided with arms 27 and 28 which extend rearwardly therefrom and support a horizontally disposed shaft The shaft 29 is provided with a beveled gear 30 which meshed with the gear 25 and which is loosely disposed upon the inner extremity of the same and which is provided with a spring actuated pawl 31 to cotiperate with a ratchet 32 rigidly mounted upon the shaft 29 adjacent the outer face of the beveled gear 30 to actuate the gear 30 upon the rotation of the shaft 29 in one direction. The shaft 29 is provided with a drum 33 about which is coiled a cord or strap 3% having one extremity extended downwardly and engaged with a hook 35 disposed upon the rear edge of the seat 36 of the chair. The opposite extremity of the cord at is enga ed with the upper end of a coil spring 37 which is rigidly secured at its opposite extremity to the back 10 of the chair at a point beneath the drum 33. F or the nurpose of insuring the positive rotation or the drum 33 the shaft 29 is provided with a torsional spring 38 which is disposed thereaboutand is secured at its inner extremity to one end of the drum 33 while its opposite extremity is pivot-ally attached to the arm 28 of the bracket 24-.

The operation of the device is as follows z-JVhen the back 10 is swung forwardly the cord 34L is drawn taut at its outer extremity and the spring 37 in conjunction with the spring 38 is placed under tension by the rotation of the drum 33 in order to tighten the cord 3%. When the chair back 10 is returned to its downward position the cord 34 is relaxed from the hook and permits the rotation of the drum 33, shaft 29, ratchet 32 and the gear 30 through the medium of the pawl 31, thereby actuating the gear 25 and shaft 19. This rotation of the shaft 19 causes the pinion 17 to be rotated through the operation of the beveled gear 18, thus producing the rotation of the rollers 15 and 16 and thereby feeding a new portion of paper from the cylinder 13 upon the head-rest 11. The barber is now permitted to grasp the depended extremity of the paper strip 12 and to draw the same backwardly against the teeth 23 when the same may be conveniently torn from the strip 12 and used for lather purposes. This action is repeated upon each operation of the chair back 10 and it is thus seen that each customer will be supplied with a new portion of paper upon the head-rest This device may be applied to dentists or other chairs of a like nature where it is desired to incorporate a sanitary device which is automatic in operation.
